Workshop – Fundamental Physics in Space with Quantum Sensors

We are organizing an Aspen Center for Physics (ACP) winter workshop on Fundamental Physics in Space with Quantum Sensors, to be held February 22-27, 2026 in Aspen, Colorado, USA. The goal of this workshop is to bring together the fundamental physics, quantum sensor, and space instrument communities in order to brainstorm ideas for space missions with quantum sensors that can shed light on physics beyond the Standard Model.

Two Technical Events for the Price of One

ITM is the ION’s winter meeting with peer-reviewed technical papers related to positioning, navigation, and timing and includes the ION Fellows and Annual Awards presentations.

PTTI is the technical conference designed to disseminate and coordinate PTTI information at the user level; review present and future PTTI requirements; inform government and industry engineers, technicians and managers of precise time and frequency technology and its problems; and provide an opportunity for an active exchange of new technology associated with PTTI.
